SUPPLEMENTAL OILER FOR JOURNALS.

Specification of Letters Patent. Paijenijed July 1919.

Application filed December 3, 1918. Serial No. 265,142.

T 0 all whom it may concern:

Beit known 'that I, -DANIEL M. MAHANEY, a citizen 'of the United States, and residing at New York, in the county of New York and State of New York, have invented certain new and useful Improvements in Sup plemental Oilers for Journals, of which the following is a specification, such as will enable those skilled in the art to which it ap pertains to make and use the same.

This invention relates to the oiling mechanism of the journals of railway wheel shafts, axles or thelike, and particularly to oiling mechanisms of this class in the form of. boxes in which the journals are mounted; and the object of the invention is to provide a'supplemental means which is automatic in operation for oiling such journals when the oil in said boxes is consumed and to re-oil said journals before they become what is known as hot-boxes caused by the lack of lubrication; and a further object of the inventionis to provide a supplemental oiling mechanism of the class and for the purpose specified which is simple in construction and operation and efiicient in use.

The invention is .fully disclosed in the following specification, of which the accompanying drawing forms a part, in which the separate parts of my improvement are designated by suitable reference characters in each of the views, and inwhich Figure 1 is a side diagrammatic view of a truck of a railway car and indicating my improvement connected therewith;

Fig. 2 a partial section on the line 2-2 of Fig. 1 on an enlarged scale and with parts in a different position; and,

Fig. 3 a partial section on the line 33 of Fig. 2.

In Fig. 1 of the drawing I have shown at 10 one form of truck usually employed for supporting a railway car, the opposite ends of the truck being provided with boxes 11 in which the journals 12 are mounted, said journals being on the ends of the axles carrying the wheels 13 of the truck 10. The end of each of the journals is flanged as shown at 14, and mounted in the top of the boxes 11 and resting upon the top of the journals 12 are the usual brasses 15 which take the thrust of the load upon the journals '12 in the usual manner. The outer portions of the boxes 11 are made hollow in form as shown at 16 and provided with openings 17 which are normally closed by covers 18.

The above described construction is similar to that common in apparatus of the class specified and forms no part of my invention and has been merely shown to illustrate one use of my improvement and, in'practice, I- provide the inner face of the cover 18 with a reservoir 19 which may be secured thereto, or formed integral therewith, and connected with one side of the reservoir '19 at the bottom thereof is a pipe 20 which extends backwardly into the box 11,'and is provided on its inner end With a valve device 21,the-discharge 22 of which is directed at right angles to the pipe 20, and in'the directiono'f the journal 12. The valve 21 is normally closed but may be opened by depressing-a headed plunger 23 inthe top thereof.

I also providea spring arm 24 which is secured to the inner face of the box lland in such position as to permit the arm 24 to strike the headed plunger 23, and said arm is normally held in a raised position by a wire or cable 25 which passesaround a pulley 26 pivoted to the wall of the box 11 as shown in Fig. 3, said wire being passed through an aperture 27 in the brass 15 at the top of the journal 12,'and the end thereof connected with a small piece of Babbitt or similar material 28 on the inner arc-shaped face of the brass 15, and which has a bearing on the outer face of the journal 12.

The piece of Babbitt or other metal serves to retain the wire or cable 25 in connection with the brass 15 and to support the spring arm 24 in position shown in Fig. 3, and when oil in the box 11 has been consumed or the journal 12 is in need of lubrication, the heat generated by the friction between the brass 15 and journal 12 due to lack of lubrication will melt or break up the piece of Babbitt or similar metal 28 thus causing the release of the wire or cable 25, which permits the descension of the spring arm 24, and this operation depresses the headed plunger 23 and opens the valve 21 to allow the oil in the reservoir 19 to bedischarged into the box 11 and onto the ournal 12.

The bottom of the reservoir 19 is preferably graded as shown at 29 in Fig. 1, and a plug 30 is connected with the bottom of the reservoir to permit of the filling of said reservoir whenever desired. It will also be noted that the reservoir 19 with the pipe 20 and valve 21 are carried by the cover 18 of the box 11 and the parts which operate the valve 21 are carried by or mounted in.

having the usual brasses and pivoted covers,

said oiler comprising a reservoir mounted on the inner face of the cover of said box, a discharge plpe connected with said reservoir and a valve in said pipe, said valve being normally closed, means secured to the box in juxtaposition to said valve for opening the same, and means involving a fusible device secured in the inner face of the brass of thejournal for holding said first named means in an inoperative position.

' 2. The combination with apparatus of the class specified, comprising a'journal mounted inTa journal box having aipivoted cover and a brass, of a supplemental oiler comprising a reservoir mounted on the inner face of the cover of said box, said reservoir being provided with a discharge valve which is normally closed, tensional means mounted in said box in juxtaposition to said valve for opening the same, and means in- .Goples of this patent may be obtained for volving a fusible device secured in the beartaposition to and independent of said valve and adapted to open thevsame, a wire or cable connected with the free end of said arm, said wire or cable being passed around a pulley secured in the box and the end thereof secured in the inner or bearing face of said brass by a piece of Babbitt metal which has a bearing on said journal whereby when the journal becomes heated said Babbitt metal willbe melted 'or broken'up to release said wire or cable and said spring arm to permit the opening of sald valve to v discharge'the oil in said reservoir into said box to lubricatethe journal; V In testimony that I claim the foregoing as my invention I have signed my name in pres? ence of the subscribing witnesses this 2nd day of December, 1918. -s l DANIEL M. MAHANEY.
